Answer:
£7
Step-by-step explanation:
x - .2x = £5.60
.8(x) = £5.6
x= £5.6/.8
No it's not the same.
First of all, miles is used for length while mi2 is used for Area.
Second, if the length of each side is 10 miles , the total area would be 10 x 10 = 100 mi2
hope this helps
Answer:
sarah is correct
Step-by-step explanation:
there are not multiple ways to divide you can only use division and the equation is 15/2
Answer:
volume = 450 mm³
Step-by-step explanation:
Given:
- height = 18 mm
- area of base = 25 mm²
Volume of a rectangular prism = area of base x height
⇒ volume = 25 x 18 = 450 mm³
The question here is how long does it take for a falling
person to reach the 90% of this terminal velocity. The computation is:
The terminal velocity vt fulfills v'=0. Therefore vt=g/c,
and so c=g/vt = 10/(100*1000/3600) = 36,000/100,000... /s. Incorporating the
differential equation shows that the time needed to reach velocity v is
t= ln [g / (g-c*v)] / c.
With v=.9 vt =.9 g/c,
t = ln [10] /c = 6.4 sec.
